This is the lens that is now included as a kit lens with the Canon Rebel T5i and the Rebel SL1. Based on the performance of past Rebel kit lenses, it may be a bit overpriced at $249… What do you think?
B&H Photo currently has a deal on the Rebel XS and two Canon lenses that shows $669 on the product page; however, when you add it to the cart, it drops to $509.
I’m not sure how long it will last, but since the Canon DSLR and lens rebates expire later this week, I wouldn’t expect it to last past that. If you’re interested, here’s the link.
